Definitions
- the subject of the invention is a method for the removal of dampness from the walls of masonry buildings which became damp as a result of capillary rise of groundwater in the wall material, which consists in injecting of an aqueous mixture into a number of holes drilled in a building partition to be treated, the mixture includes portland cement and specially developed inorganic and organic silicate activators with an addition of an agent that controls the unfavourable convection effects in the capillary liquids which disturb the desirable process of self-organisation of crystals.
- ionic components of this injection mixture in diffusing inside the water-filled capillaries of the masonry wall material, produce a horizontal or vertical damp-proof insulation in the wall as a result of a specific crystallisation of some water-insoluble compounds, thereby sealing off the pores and capillaries in the zone of the purposely drilled injection holes
- a surfactant is added into the injection preparation, which favourably reduces viscosity of the injection preparation, thus increases diffusion rate, which results in the desirable increase in the radius of penetration of the agents that build the damp-proofing barrier in walls
- the insulation produced from domenes of crystals that are arranged in concentric spherical rings in space can be seen in a vertical or horizontal cross-section as a number of concentric rings of an increasingly greater radius.
- the performance of the barrier thus produced is of indefinite lifetime, irrespective of the initial moisture content and salinity in the walls, as the radius of penetration of the injection preparation according to the invention is the larger, the high initial moisture content in the wall.
- This property of the crystalline injection technique makes it different from all the other wall dampness removal techniques known in the art, as a greater wall moisture results there in a reduced penetration radius or in the need to resort to the expensive heat sources to pre-dry the wall prior to the injection operation.
- the method according to this invention consists in a suitable preparation of the injection mixture, which includes portland cement, an activator in the form of sodium metasilicate and/or sodium polysilicate, sodium/potassium methylsiliconate, sodium orthophenylphenolate as a surfactant, and water, the ratio by weight of the components: cement to activator preferably ranging from 1:1 to 10:0.2, whereas the ratio of sodium metasilicate, potassium metylsiliconate and sodium orthophenylphenolate and water is preferably 1:0.2:0.05:4, respectively.
- the horizontal damp-proof insulation consist in first drilling in the wall from which dampness is to be removed holes arranged on a horizontal line parallel to the floor.
- the holes 20 mm in diameter are drilled at an angle of 15-30 degrees every 12-16 cm to a depth equal to the wall thickness minus 5-10 cm. Additional water is poured into the holes thus made prior to the introduction of the injection preparation in a quantity at least equal to the volume of the holes but not more than 0.5 1 for the walls ca. two ceramic brick thick.
- the amount of the preparation introduced by gravity into the holes according to the invention is equivalent to the volume of the hole drilled.
- the holes are filled up with the same preparation and made level with the wall face using a spatula.
- the damp-proofing barrier of the crystalline kind is ati depending on diffusion rate which depends on temperature.
- the sealing effect of the preparation according to the invention consists in that the silicate ions dissolved in water along with calcium ions derived from specific dissociation of portlandite, the mineral present in portland cement, make water-insoluble calcium silicate to precipitate in the capillaries.
- a characteristic feature of the precipitated crystals is that their precipitation at the outer end of the capillary at the injection hole do not stop the precipitation reaction components to penetrate deeper into the capillary. This effect, which is unexpectedly beneficial from the technological viewpoint, is enhanced by the sealing function of the silicone compounds and the action of the fungicidal surfactant that accelerates the diffusion rate.
- the crystallisation products become arranged unexpectedly about the injection hole in the form of concentric rings that are spaced initially several millimetres and then the distance between the rings gradually increase to reach about one centimetre at a distance of ca. 10 cm from the centre of the injection hole.
- the mechanism of the reaction proceeds initially through crystallisation to form very fine crystals in the whole bulk involved in the diffusion process, and subsequently through a spontaneous process referred to as self-organisation of crystals to produce crystalline domains as well as domains not containing crystals.
- thermodynamic driving force that occurs in a homogeneous sol, admittedly being the result of a competitive growth of molecules on account of the dependence of the equilibrium constant on the radius of the molecule which is due to surface tension.
- a number of images of the structures formed are obtained which resemble the Liesegang rings.
- the formation of the whole of the barrier in its thermodvnamic mechanism reflects the so-called Prieoeinian effects (the 4 th nrincinle of thermodynamics) occurring irreversibly in states far from the thermodynamic equilibrium.

Abstract
Cette invention se rapporte à un procédé servant à éliminer l'humidité des bâtiments dont les murs deviennent humides en fonction de l'ascension capillaire de l'eau de sol, grâce à la technique d'injection de matériau cristallin. Dans ce procédé, on introduit dans des trous percés à dessein dans le mur, de préférence sur le même niveau à une distance de 10 à 18 cm entre eux selon un angle de 15 à 30 degré et préalablement imprégnés d'eau, après imprégnation additionnelle préalable à l'eau, un mélange de suspension aqueuse de ciment portland, un activateur à la silicone avec du siliconate de sodium et de l'orthophénylphénolate de sodium et de l'eau en quantité telle que le mélange possède une consistance liquide homogène et est auto-nivelant dans le récipient, pour que, au moment de son introduction par gravité dans les trous d'injection, aucun bouchon d'air ne puisse se former.
